FDISK

This is the main screen used during the time running FDISK. This would also be the first screen if your computer operating system does not support FAT32. From this window you will have the capability of setting up or removing partitions from your hard drive(s).





------------------------------------------------------------------------------------------
Using the options within this screen you will be able to create the various different partitions. These options will only allow you to create FAT16, and FAT32 partitions if supported and you pressed Y for Yes to enable large disk partitions. If you are attempting to create NTFS partitions, use Windows NT Disk Manager.

1. Create Primary DOS Partition - Choosing this option you will be prompted to use maximum space. If you specify yes, this will use up to 2 GB if creating FAT16 partitions, or up to 32 GB if using FAT32. If you choose no you will be able to specify how large you would like the partition to be. NOTE: you will need to create primary partitions before being able to create Extended or Logical DOS partitions.2. Create Extended DOS Partition - If you are using FAT16 and have a 2 GB or higher hard drive or have only specified a small portion of the hard drive as the Primary partition, use this option to create the Extended DOS partition(s) (other drive assignments). The Extended DOS partition will be used to hold the Logical DOS drives; therefore, use the maximum space left on the hard drive.3. Create Logical DOS Drive(s) in the Extended DOS Partition - This option is used after you have created an Extended DOS partitions. Once the Extended DOS partition has been created you then can specify the sizes of other partitions you wish to create.Example of what has been explained above:Bob has a six GB hard disk drive and wishes to divide the hard drive into three partitions, each using FAT 16.Step 1. If prompted to use Large Disk support, press N for no because Bob does not want FAT32, he would like FAT16.Step 2. Choose option one to create a Primary partition. Once prompted to use maximum space, press N for no and specify 2 GB as the size of the primary partitions Step 3. Once the primary DOS partition has been created, choose option two to create an extended DOS partition. Use the maximum space, which would be four GB because two GB has already been used for the Primary Partition.Step 4. Create two logical DOS drives, each being 2 GB.Step 5. Reboot the computer and format each of the drives to allow them to be accessible.Assuming Bob only had one hard drive, doing the above Bob would have:Drive C: Partition 1 (Primary) FAT 16Drive D: Partition 2 (Extended/Logical) FAT16Drive E: Partition 3 (Extended/Logical) FAT16Note: Once a primary partition has been created please ensure that you set the partition as an active partition.
-----------------------------------------------------------------------------------------------
Within this screen you will have the capability of deleting pre-existing DOS partitions. If you currently have no disk space available on your hard drive and wish to create additional partitions, you must first use this screen to delete the partitions and then you will be able to create partitions. NOTE: if you delete partitions, any information on those partitions will be erased and CANNOT be recovered.
1. Delete Primary DOS partition - Use this option to delete your main primary partition. However, if you currently have any Extended / Logical DOS partitions, you must delete these partitions before you will be able to delete the Primary DOS partition.2. Delete Extended DOS partition - If you have your computer partitions into more than one drive, use this option to delete the extended dos partition(s). You must delete the Logical DOS Drive(s) before you can delete the Extended DOS partition.3. Delete Logical DOS Drive(s) in the Extended DOS Partition - This option would be used first if you have extended DOS partitions and wish to delete the extended partitions.4. Delete Non-DOS Partition - This option is usually used for partitions that either have been created by third-party applications, such as a DDO or other operating systems such as IBM Warp, Unix, as well as various other operating systems.Example of what has been explained above:Bob has created three partitions on one hard disk drive; however, he would like to delete them all.Step 1. Delete the two logical DOS drive(s) in the Extended DOS partition with Option number three.Step 2. Once the Logical DOS partitions have been deleted, choose option number two to delete the extended DOS partition.Step 3. Choose option one to delete the Primary partition.Step 4. Reboot the computer to allow above changes to take effect.
------------------------------------------------------------------------------------------------
Within this screen you will be able to see what is currently being used and how your computer hard drive is setup. NOTE: If you see invalid information such as !, *, &, % as the Volume Label, the Partition, or the Status, it is a good possibility that you may have a VIRUS on the computer.



The above picture displays information about Extended DOS partitions; if, however, you only have a Primary DOS partition, your screen would only display the partition information and you will only have the option to Esc out of the screen.
------------------------------------------------------------------------------------------------This option is only available if more than one Hard Drive is installed within the computer. In the below picture you can notice that we have 3 hard drives listed within this computer. Disk 1 has two partitions, which are C: and D: The hard drive's total space is 3 GB. Then Disk 2 has three partitions E:, F:, and G: and the hard drive total space is 6668, or 7 GB. As you notice in the below picture, there is also a Disk 3, this is actually an Iomega Zip Drive hooked up to the IDE controller on the Motherboard. Other media that is connected to the IDE controller within your computer will usually be displayed within FDISK; however, this is not a hard drive and does not need to be FDISKed, this is why 95MB is free. An exception to this rule would be a CD-ROM.

Latest Model of a Motherboard


EPoX 5EDAI — a Motherboard on Intel 915P
Intel 915P chipset (i915P Northbridge and ICH6 Southbridge)
The motherboard market has come to a standstill on the threshold of models based on the new line of Intel 965 chipsets. Indeed, the entire computer world is waiting for the appearance of Intel Core 2 processors in desktops. These processors with the new microarchitecture are officially supported only by i965/975-based motherboards. (i975X is quite an expensive chipset without unique features; besides, not all first revisions of motherboards will work with Conroe.) So during this lull we'll publish reviews of old motherboards that we missed. We'll also expand our horizons, as we have been pointed at a growing number of reviews about products from a limited number of manufacturers.
EPoX 5EDAI returns us to the past. To the i915P chipset, which was launched nearly two years ago… Many lances were broken over the sudden upgrade to new Intel standards. DDR2 memory was expensive and slow, no one wanted PCI Express and that stupid socket… But now this budget motherboard from EPoX arouses no feelings of inferiority. Fortunately, such memory got cheaper (DDR2-533 is nearly cheaper than DDR400), all new video cards are designed for PCI Express only, and no one remembers how the old socket looked like. 5EDAI is a budget solution, but it does not mean that this solution is bad. This model offers flexibility in memory usage (two slots for DDR and two for DDR2 — of course, four slots of the required standard would have been better, but different users need different things) and peripheral slots: 3 x PCI (all of them will be available even after you install a monstrous video card), 2 x PCIEx1, one graphics slot (how many of your friends have a SLI/CrossFire computer?). Additional controllers are kept to minimum, but there are some nice features (like an integrated POST controller), passive chipset cooling, and as a result - a low price. This model also has drawbacks, of course — it does not support dual-core processors (all cores newer than Prescott) and DDR2-667 memory (and higher), but it's a questionable drawback. Scanty functionality has a good effect on the PCB layout: there are absolutely no problems with arranging a few connectors for peripheral devices and expansion cards. IDE and FDD connectors are located behind PCI slots to facilitate access in a small PC case, but memory slots stand in lone conspicuity, which certainly makes it easy to handle them. A main power connector in the center of the board is a peculiarity of most EPoX models, which has a positive effect on voltage regulators, though it poses some problems with laying a power cable. Besides, this connector is very close to the PCIEx16 slot on this motherboard, so it will fight for the surrounding space with a video card with a bulky heatsink. Access to jumpers is not hampered when the motherboard is installed into a PC case. But both of them are placed close to other elements: one of them is near a PCI slot, the other - to the display of the POST controller. So it's not very convenient to manipulate them. Brief description of their functionality is provided on the PCB (sometimes in unexpected places).
The 4-phase switching voltage regulator of the processor incorporates seven 1800 uF capacitors (Luxon) and four 560 uF ones (Sanyo). The motherboard is also equipped with a voltage regulator for memory, reinforced with L elements and several 1000 uF capacitors. The PCB has empty seats for a chassis intrusion sensor and a connector for a Game port on a bracket. It may be a peculiarity of our sample, as the PCB of this model is unique in the line of EPoX products. Other motherboards from this company, based on the same chipset family, usually offer better functionality (Gigabit Ethernet + RAID of SATA drives + IDE RAID) and designed for DDR memory (support for two memory types is a unique feature of the 5EDAI). Motherboard dimensions — 305x245 mm (full-sized ATX, nine-screw mount, all motherboard edges are firmly fixed).
System monitoring (Winbond W83627THF, according to BIOS Setup)
CPU core, memory, chipset, battery voltages, +3.3 and +12 V and +5 V Standby
RPM of 3 fans
CPU and board temperatures (by the corresponding embedded sensors) and an external thermal sensor, which is connected to a special header on the PCB — EPoX remains one of the few companies that still include this useful feature into its models; unfortunately, our bundle lacked the thermal sensor
Chassis Smart Fan Control — automatic control of rotational speed of a system fan depending on a temperature inside a PC case (this function is mostly for offices, you can specify a desired temperature within 35—55°C)
CPU Fan Auto Control — "classic" CPU fan speed control depending on CPU temperature (the budget model uses the simplest method: you specify desired temperature, the other parameters are configured automatically).
Onboard ports, sockets, and connectors
Processor socket (Socket 775, officially supports all modern Pentium 4 (5xx/6xx series) and Celeron D (3xx series) processors, permissible bus clock — 533/800 MHz)
2 x DDR SDRAM DIMM (up to 2 GB DDR200/266/333/400, dual-channel mode supported) and 2 x DDR2 SDRAM DIMM (up to 2 GB DDR2-400/533, dual-channel mode supported) — different memory types cannot work together!
PCIEx16 for a video accelerator
2 x PCIEx1
3 x PCI
Power connectors: standard ATX 2.2 (24 pins, you can use a usual 20-pin connector), 4-pin ATX12V connector for a processor
1 x FDD
Chipset-based IDE connector (Parallel ATA) for two ATA100 devices
4 x "chipset-based" SATA (Serial ATA) for four SATA150 devices
2 connectors for brackets with 4 additional USB ports
1 x CD/DVD audio connector
AUX-In connector
S/PDIF-In/Out
Connectors for analog audio ins and outs on the front panel
IrDA connector
3 fan headers, all of them support rpm control, one of them is a 4-pin header (for a processor fan) offering more accurate fan speed control (if this option is supported by a cooler).
